In response to overwhelming demand, Mr Ollivander, world-famous wandmaker, has created a means of wand allocation (or, more accurately, wizard selection) involving nothing more than seven simple questions.
Give honest answers to these enquiries, and Mr Ollivander will be able to tell you which of his handcrafted wands would most like to call you master or mistress.
Certain combinations of wand and core are more unusual than others, but you can rest assured that if you have given truthful responses to Mr Ollivander's carefully constructed questionnaire, you and your selected wand will enjoy a long and fruitful association.
Strict rules govern wand-trade, so a personal visit to Ollivanders Wand Shop will still be necessary if you would like to take physical possession of the wand that has chosen you.
